I like NovaKatherine best. I think its good to balance out an unusual firstname with a more common middle, to give your child options if she is shy and doesn't want to stand out from the crowd so much. But the only one from your list I really dislike is NovaAveri. NovaAvery I would like more.

katieydenberg; I think Avery is too masculine, so I prefer averi, or Averie.
capturedcastle; Would NovaHarper really be too close to Parker? I mean, Parker that's her FN and Harper would be the MN of another child..
hermione_vader; yeah..Katherine isn't something I normally would choose. but my mom suggested it and she really loves it, so it grew on me
oosoposh; thank you! Those are in my top 4.
